Conversion to go by remote control

I gave my son the Grand Prix racer for enrollment.
Today he has come up with the idea of ​​4x4 off-roader to lock out the engines.
The functions without driving are pretty boring.
I noticed that it would have to go pretty easy to turn the F 1 in a remote-controlled vehicle. This requires only a rod, a wheel and the Motorenset.
My son is excited. At last he can already super also go by anyway Lego Technic model.
